RUBBING UP ELECTRICITY

By: Lindsay E.

Page 2: Lindsay e.

I WANTED TO FIND OUT IF THE NUMBER OF RUBS ON A BALLOON WILL AFFECT HOW LONG THE STATIC CHARGE WILL LAST.

My Hypothesis is: I don’t think it will matter how many times you rub the balloon.

Page 3: Lindsay e.

First I got a balloon. I started by rubbing it on the carpet 1 time. Then put it on the wall to see if it would stick. If it stuck I timed it to see how long.

I did the same thing 4 times. Each time I rubbed the balloon 1 more time than the last.

I did this whole experiment 3 times, so I could compare the results.

MY RESULTS

My guess was not really right or wrong. Most of the time the more you rubbed it the longer it would stay. But there were a couple of times that were different.

WHAT I LEARNED

I read this book on static electricity. I learned that everything that turns on has electricity. Some electricity can be dangerous, like lightning. I learned that rubbing a balloon picks up electrons and when they run out the balloon falls off the wall. The more times you rub it the more electrons it picks up, so it should stay on the wall longer.
